// Usage in vanilla CSS:
|
|
// - <div class="grid-4"> for an equal fourth columns grid container
|
|
// - <div class="grid-2-1"> for an uneven columns grid container
|
|
|

// Usage with preprocessors : if you're using Sass, you can config grids variables :
|
|
// n = number of columns (default = 4) / g = gutter value (default = 1em)
|
|
// example : .grid-perso { @include grid(12, 10px); }
|

// ... or uneven grids :
|
|
// left = left ratio column (default = 2) / right = right ratio column (default = 1)

// example : .grid-perso { @include uneven-grid(2, 1, 10px); }
